Careful when giving out such vague advice...there's a little more involved. One can only safely mix up to a 30% mix of toluene or xylene into pump gas. And add 1 oz of Marvels Mystery oil/gal of either of the aforementioned is recommended. Both of these are very "dry"...the MMO helps keeps seals from drying and cracking.

Personally, I'm running a 94 octane mix: 1.5 gal xylene (117 octane) and 1.5 oz MMO with 11.5 gal 91 octane. This is safe to use in a daily driver.
